Serious Sam Double D XXL

Serious Sam Double D is a 2011 side-scrolling shooter game developed by Mommy's Best Games and published by Devolver Digital. The game follows Sam "Serious" Stone traveling through various historical settings to destroy the hordes of his nemesis, Mental, and its teleportation beacons. As Sam, the player navigates 2D levels and can use the "gun stacker" to create vertical stacks of up to six weapons that are fired simultaneously. Enemies appear from all sides, and their corpses can be used as platforms. Announced in March 2011, Double D was created as part of the Serious Sam Indie Series to promote the release of Serious Sam 3: BFE. Devolver Digital requested a "Contra on acid", and the designer Nathan Fouts modeled the game after Mommy's Best Games's first release, Weapon of Choice. Double D debuted for Windows in August 2011. Serious Sam Double D XXL, an expanded version, was co-released by Mastertronic for the Xbox 360 via Xbox Live Arcade in February 2013, introducing more content and a local cooperative multiplayer mode. This version was ported back to Windows and released in October 2013 as a free update for the original game. Both versions of Double D received mixed reviews. The gun stacker was well received, although a lack of depth was noted. The sound design was praised. Conflicting opinions were raised regarding the game's writing, level design, music, and visual style. Its repetitiveness and technical issues were criticized.
